Hello Barry !

Some snippets from the cowbuilder log:
checking for mpg123_init in -lmpg123... no
configure: WARNING: **** mpg123 not found !
checking for alcGetIntegerv in -lopenal... no
configure: WARNING: **** OpenAL not found !

It seems you've forgotten build-deps.
Moreover,
dh_install -a --list-missing
lists *many* files installed to debian/tmp but not part of any package.
Apart from that, it seems to work reasonably fine. Could you check out
these problems, please ?
